It’s all about the river
The Spokane Valley-Rathdrum Prairie Aquifer is recharged by precipitation, adjacent lakes, and the Spokane River. Almost 50% of the recharge comes from the river! Pumping from the SVRP aquifer can lower the amount of groundwater that seeps into the Spokane River.
2017 Residential Use in a nutshell: ■ Total Residential Use: Total Residential Use: 8.9 Total Residential Use: Billion Gallons ■ Total Summer Use: Total Summer Use: 5.1 Billion Total Summer Use: Gallons – 57.5% of all water is used outdoors

pathways?
greater amounts of solar heat than turf and mulch, and these surfaces radiate more heat during the day and into the evening. Anything near asphalt or concrete will have a high microclimate. Have you ever noticed how much harder it is to keep these areas green?
This area needs lots of additional water compared to the rest of the yard due to no shade and its Southwest location

Make Sure to include:
Sheet Mulching
■ Remove several inches of turf and soil from the edges
for the mulch to lay without sluffing off on your sidewalk, curb, lawn etc. ■ Wet the lawn are to be removed and cover it with a few layers of newspaper or cardboard ■ Water again and add an additional layer with a layer
■ Once layers are placed, water well and cover with 3- 6” of mulch ■ Can be planted in immediately, however waiting for the grass to die will make digging a bit easier
Mechanical Stripping Solarization
■ Water the grass well before placing plastic ■ Make sure that the plastic cover is air tight, use rocks or soil to hold down edges ■ Leave in place for 6-8 weeks ■ Can Rent ■ Need to dispose of turf- can’t go in your green bin ■ Removes quality growing soil ■ Consider using it to make mounds in your new landscape
can collect to slow runoff from your SpokaneScape to the street,

Inline Emitter Tubing
Compression Fittings Insert Fittings
■ Slowly applies water directly to the soil where very little is lost to evaporation & run-off ■ Because the water is applied to the soil and under mulch, blown-in weed germination is limited ■ Simple to install, requires no trenching ■ Requires a filter to keep the emitters from clogging ■ Lays on to top of the soil and is covered with mulch ■ Does not need to be blown out in the winter
Drip Emitters
Emitters
■ Slowly applies water directly to the soil where very little is lost to evaporation & run-off ■ Waters desired plants only which helps to reduce weeds ■ Simple to install, requires no trenching ■ Requires a filter to keep the emitters from clogging ■ Lays on to top of the soil and is covered with mulch ■ Should not need to be blown out in the winter as you may pop emitters off.
Parts You Will Need
■ Timer ■ Backflow Device ■ Filter ■ Pressure Regulator ■ Swivel Adapter ■ Drip Tube Very simple to install, and costs $80- $90

■ Keeps moisture and temperatures consistent ■ As it breaks down, mulch adds to the
■ Helps reduce water runoff ■ Suppresses weeds and saves you time! ■ Types: wood chips, compost, decomposed granite, river rock, and bark.
Gravel Rock Mulch
■ Clean your filters ■ Check emitters and equipment ■ Use organic fertilizer or compost ■ Weed by hand every few weeks – Make sure to pull them before they go to seed – More mulch will help prevent weed growth ■ Winterize!
